INR3716 TECHNICAL MATHEMATICS
3 Credit Hours
This course is open to students on the college level in either the freshman or sophomore year and to area high school vocational students.
INR 3716 - Technical Mathematics (3 hrs.)
This course is designed to prepare the student for dealing with the problems of industry. It will briefly review basic arithmetic and then move on to application problems (word problems) taken from various industrial disciplines. The focus will be on manipulating weights, measurements, and formulas from basic math through an introduction to algebra, geometry and trigonometry.
This course is open to all students who are accepted in technical programs.
This course is designed to help the student increase their knowledge concerning applying mathematics to the world of work.
On completion of this course the student will be able to successfully apply basic math skills to related problems in the vocational area.

Maximum class size:
Based on classroom occupancy.
Course Time Frame:
The U.S. Department of Education, Higher Learning Commission and the Kansas Board of Regents define credit hour and have specific regulations that the college must follow when developing, teaching and assessing the educational aspects of the college. A credit hour is an amount of work represented in intended learning outcomes and verified by evidence of student achievement that is an institutionally-established equivalency that reasonably approximates not less than one hour of classroom or direct faculty instruction and a minimum of two hours of out-of-class student work for approximately fifteen weeks for one semester hour of credit or an equivalent amount of work over a different amount of time. The number of semester hours of credit allowed for each distance education or blended hybrid courses shall be assigned by the college based on the amount of time needed to achieve the same course outcomes in a purely face-to-face format.
